Administrator Info (Club 8443)

I am looking into improving our club's FTH site and one thing I found was a name on the Administrator Info tab that I didn't recognize. I tried emailing the person but got no response. What is the role of the Administrator and can I change it to be a current member of the club? Thank you.

it you want to change the site admin please follow these docs.

Changing site administrators when the previous one is no longer available

Thank you for the information. What is the role of the Administrator? Is it supposed to be one person that has access as administrator to the site? Our club has shared the password to a few officers to handle administrative duties. 
Also, looking at the instructions for changing the administrator, I see that an email will be sent to the current and proposed administrators before approval. Does the current administrator need to take any action? I ask because I have not heard from the current administrator when I tried to contact her so I don't want that to be a bottleneck in the change process.

Please read the the documentation.

Yes one admin who can grant permission to up to 3 officers
